BACKGROUND OF THE INVENTION Field of the Invention

The field of the present invention relates to a method and apparatus for repairing damaged, deteriorating, or fractured bones in the mid-foot region. More particularly, the present invention relates to both a method and device for treating the bones in the medial column of a human foot that are effected by Diabetic Charcot mid-foot collapse, LisFranc injuries, and the like.

Description of Related Art

The utilization of implants, such as intramedullary nails, rods, and screws is well known in the art, specifically in the treatment of long or large bone fractures. Implants are those devices which may be inserted into any foreign body, with intramedullary nails being the most common type of implant. Intramedullary nails have been limited in their application to long or large bones and such use has been widely known for long or large bones of the upper extremities (humerus, radius, ulna) and lower extremities (femur, tibia, fibula). Use of intramedullary nails allows physicians to secure fractured bones, maintain a desired length, and prohibit rotary motion while the bone heals and has time to rehabilitate. Intramedullary nails are also used for the fusion of bones.

Intramedullary nails are adapted for insertion into the medullary canal of a bone or bones, which may be reamed or left unreamed. Reaming is achieved by drilling out the medullary canal of the fractured or deteriorating bone, where the nail is inserted to stabilize and position the bone for healing. A cannulated reamer diameter generally runs in size from 7 mm and 18 mm, at increments of 0.5 mm A medullary canal is generally reamed at 0.5 mm larger than the diameter of the nail to be inserted, so the bone is not damaged when the nail is inserted. Such reamers are well known by those with skill in the art.

Much of the prior art implant and intramedullary nail systems comprise intramedullary nails having fastener holes at both the proximal and distal ends for the insertion of fasteners, or locking screws. Fasteners include all attaching means by which an implant may be attached to bone. Such fasteners are inserted through a fastener hole or slot, also described as transfixation holes and screw holes. The use of locking screws is optional depending upon the severity of the bone damage. An intramedullary nail implanted with at least one fastener or locking screw both proximally and distally completely locks the nail in place (also known as static locking). Static locking neutralizes rotational stresses while preventing shortening of the limb. An intramedullary nail implanted with only one locking screw either proximally and distally, partially locks the nail (also known as dynamic locking). Dynamic locking neutralizes rotational stresses on one side of the fracture site while permitting axial loading. To surgically promote fusion of bone segments together, some means of static locking is required. Such holes and screws may also be adapted for the central portion of the nail or implant.

Several nails exist with fasteners or locking screws that are much longer in shape, described as lag screws, jigs, or nail heads, which further prevent the rotation of separated bones. Other nails have spacers to absorb stress associated with repetitive, natural impact. All such devices are focused on securing bone fragments during the process of fracture healing. Other methods for attaching the nail to the bone including the use of longitudinal pins, or the use of cement injected through a cannula in a nail to secure one end to the nail.

Various types of implants and intramedullary nails exist in the prior art, each composed of different materials and having different shapes with various degrees of functionality. Many nails are formed from either a slid rod metal or a more flexible sheet metal. Several nails have been proposed which form a rod material containing a central longitudinal bore disposed throughout (cannulated). Many nails have a number of longitudinal grooves cut along the rod (known as fluting), which allow for more rapid revascularization within the bone. Accordingly, nails made of various material and those having a differing array of shapes already exist and may be easily manufactured. A study of the geometrical properties of different nails is discussed in the article “Geometrical Properties and Torsional Fatigue Life of a Tibial Interlocking Intramedullary Nail Segment” Journal of Orthapedic Trauma, Vol. 12, No. 1, pp 8-15, and is incorporated herein. Also, different tibial nails were compared in the article “Biomechanical Study of Nine Different Tibia Locking Nails” Journal of Orthapedic Trauma, Vol. 10, No. 1, pp 37-44, which is also incorporated herein.

Recently, implants and intramedullary nails are being fabricated using bioactive, biocompatible, and bioabsorbable material. Such nails are made from bioabsorbable polymers, copolymers, or polymer alloys that are self-reinforced containing ceramic particles or some type of reinforcement fibers. These implants and nails, as well as others, can also be made to be porous. The knowledge exists today to create human replica bones, grown in animals utilizing human gene technology, for ultimate use in humans, and such material may be a viable supplement for standard intramedullary nails of today. Such techniques should also be considered as an appropriate part of the present invention.

While there is much in the art regarding implants and intramedullary nails, there was no prior art found dealing directly with implants or intramedullary nails for the mid-foot region, or medial column of a human foot. Such a nail may likely have any or all of the similar properties, features, and characteristics of the above mentioned nails, but would have to be much smaller in length and thickness (for axial support) to accommodate the smaller bones of the mid-foot region. The prior art referring to intramedullary nails, for the most part, refers to nails which are used in much larger bones. Such art includes:

BRIEF SUMMARY OF THE INVENTION

The present invention is directed to a device and method for treating and fixation of deteriorating, damaged, or fractured bones in the mid-foot region (navicular, medial cuneiform, intermediate cuneiform, lateral cuneiform and cuboid bones). More specifically, the present invention relates to the treatment and fixation of certain bones in the medial column (specifically, the medial cuneiform and navicular bones) of a human foot. Such bones are not considered long or large in the traditional sense as are those specified above. An apparatus, such as an implant, or more specifically an intramedullary nail, is inserted through and attached to both the first metatarsal and talus bones to secure the medial cuneiform and navicular bones in place. This procedure also is expected stabilize all the bones in the mid-foot region. After appropriate reduction and compression, such a method and device would ultimately allow for fusion of the bones. In accordance with the present invention, one device used to achieve the above described method is a cannulated intramedullary nail that is round in cross-section, having an elongated body with a proximal head portion, intermediate portion, and distal tapered end portion. The proximal head portion has one or more transverse holes, ideally three, with an intermediate portion having one or more transverse slots, ideally two, and a distal portion having one of more transverse holes, ideally two. Such transverse fastener holes or slots are used for insertion of fasteners (including interlocking cortical screws or transfixation screws), which ideally may be attached to the first metatarsal and talus bones to secure the nail in place. Slots are adapted for the central portion of the nail for the insertion of fasteners into either the navicular or medial cuneiform, depending upon the condition of either of the two bones.

One object of the present invention is to provide an implant or intramedullary nail for the treatment and fixation of those bones within the mid-foot that are subject to damage, deterioration, or fracture that may result from diabetes related diseases, including but not limited to, Charcot foot. More than 16 million Americans have diabetes, of which approximately 54,000 patients underwent lower extremity amputations in 1990. The five-year mortality rate for diabetics has been reported as high as 70%. Approximately 800,000 Americans develop diabetes annually. The cost of caring for diabetes now exceeds S137 billion per year, or approximately 30% of the annual Medicare budget. Diabetic neuropathy ultimately results in deterioration of the bones in the foot. Such deterioration of those bones in the mid-foot region leads to the collapse of the foot, fracture of those bones, or both. The prevalence of Diabetic Charcot joints has been reported to be from 0.08% to 7.5%. The average age of onset is approximately 57 years with the majority of patients in their sixth and seventh decades. The average duration of diabetes with a diagnosis of Charcot arthropathy is 15 years, with 80% of the patents being diabetic for more than 10 years. Bilateral Charcot arthropathy has been reported between 5.9% to 39.9%. Incidence of Diabetic Charcot arthropathy appears equally among men and women.

Diabetic foot treatment to date has been limited to amputation, special casts or shoes which alleviate the deformity, and surgical intervention to strengthen the foot. An article describing an overview of diabetic foot problems is “Diabetic Neuropathic Osteoarthropathy: The Charcot Foot” Chapter 16 of The High Risk Foot in Diabetes Mellitus, edited by R. G. Frykberg, © Churchhill Livingstone Inc., 1991, and is incorporated herein. Amputation of the opposite extremity is frequently indicated within one to five years of the primary amputation. Surgical intervention has been restricted to the use of screws and plates since most bones in the foot are quite small. Methods used to repair larger bones with devices such as intramedullary nails have not been utilized in this area until now.

The medial column of the foot is comprised of six osseous components (distal phalanx, proximal phalanx, first metatarsal, medial cuneiform, navicular, and talus). The longitudinal arch of the foot is maintained by these bone segments and their supporting ligaments, tendons, and surrounding musculature. Additional support comes from the transverse arch and the interlocking of the osseous components. The medial column of the foot is the most commonly affected in the diabetic by sympathectomy-induced hyperemia associated with repetitive minor trauma resulting in mid-foot dislocations and/or fractures known as Diabetic Charcot deformities.

Treatment of foot and ankle Charcot deformities currently consists of nonsurgical (non-contact casting, orthotic bracing, and shoe gear) and surgical stabilization (k-wires, screw/plate fixation, and external fixators). Recently, implant and intramedullary nail fixation has been utilized to stabilize the ankle/subtalar joint complex. Present treatment for medical column/mid-foot deformities requires extensive surgical exposure with appropriate internal screw/plate fixation devices. One advantage of using an implant or intramedullary nail for treatment and fixation of these bones, is the limited surgical exposure that is required with only several small incisions, as opposed to the more invasive exposure resulting from opening the entire foot for insertion of several internal screws and plate devices. Also, the successes of screw and plate fixation is minimal at best.

Although prior art nails have found varying degrees of success in the treatment of long bone fractures and hind-foot arthrodesis, there remains a need in the field for an intramedullary nail specific for fixation of the medial column of the foot. This device will substantially reduce, if not eliminate many of the present complications encountered with Diabetic Charcot foot reconstruction. Such a device would provide fixation and stabilization of the Diabetic Charcot foot preventing future mid-foot collapse and ultimate limb loss. An intramedullary medial column nail and method of utilization would provide stabilization to the medial column of the foot, eliminating excessive operating time, anesthesia exposure, implant failure, long hospital stays, and reduce overall medical cost leading to early rehabilitation and ultimately limb salvage.

The present invention specifically relates to the fusion, and eventual rejuvenation of the bones in the mid-foot region which deteriorate because of diabetic neuropathy. The method comprises insertion of an implant or intramedullary nail through the medial cuneiform and navicular bones, which are most susceptible to deterioration, and securing the nail with locking screws to the stable first metatarsal and talus bones. This is one method for securing, fusing, and repairing the medial cuneiform and navicular bones and represents one embodiment of the present invention.

The present invention utilizes an intramedullary medial column nail fixation apparatus ideally being cylindrical and cannulated, and made from either titanium, a bioabsorbable material, human or animal bone, or equivalent. The nail ideally would have a number of proximal and distal fastener holes (transfixation or interlocking holes) for securing the IM medial column nail to the appropriate osseous cortical structures of the foot. An important feature of the present invention of the IM nail is its ability to function as an internal load-sharing device along the medial column of the foot. The nail acts as an internal splintage while the bones are mending, and is used to bring into alignment microfractures that may exist. The proximal portion of the nail may have a tapered tip to aid in insertion, and at least one fastener hole (ideally two) for the insertion of fasteners to fixate the neck of the talus to the implant or nail. The intermediate portion ideally has two slots to accommodate for any bone loss of the navicular and medial cuneiform, and to allow for the possible insertion of a fastener if the bones are healthy enough. The distal portion has at least one fastener hole (ideally three) for the insertion of fasteners to fixate the nail to the first metatarsal.

The present invention may also make use of a specialized thin walled tubular chisel system for removal of first metatarsal head articular cartilage for nail insertion 30. This maintains the integrity of the first metatarsal head by removing only an appropriate sized plug of bone according to the diameter of nail being used. The plug of articular cartilage and underlying bone can then be replaced and fixated after insertion of the nail. Such a chisel system may be similar to one that has been used in osteochonral autograph transfer.

In addition, another embodiment of the present invention calls for the use of a compression system that incorporates a depth gauge device which may be used to determine the amount of compression achieved. This device would eliminate the need for guessing or “feeling” the correct amount of compression required. A depth gauge would exist either on the implant or jig apparatus with a ruler type measuring means for gauging the amount of travel in the nail back up the intramedullary canal towards the phalanges. Compression could then be determined to a specified length of travel of the nail back up the canal during compression.

DETAILED DESCRIPTION

The following description will explain the embodiments of the invention, beginning with a device used for treating deteriorating or damaged bones in the medial column of a human foot, and concluding with the method for treating deteriorating or damaged bones in the medial column of a human foot. Both the first and second figures are skeletal outlines of a human foot, depicting the device therein and the resulting orientation of the bones by using the method specified below.

FIG. 1 is a top down view of a right human foot, depicting the bones therein and an implant or intramedullary nail 10 running through the mid-foot region. The implant or intramedullary nail 10 runs through the medullary canal of first metatarsal 7, medial cuneiform 3, navicular 2, and talus bone 1. The talus bone 1 makes up the lower part 20 of the ankle joint where the proximal end 11 of the implant or intramedullary nail 10 is attached with at least one fastener (or locking screw, with two depicted in FIGS. 1, 14 & 15). Next to the talus bone, opposite the rest of the ankle bones, are the tarsal bones which include the navicular 2, medial cuneiform 3, intermediate cuneiform 4, lateral cuneiform 5, and cuboid bones 6. The medial cuneiform 3 and navicular 2 bones are those most affected by the Diabetic Charcot foot disorder, which causes deterioration and possible collapse as a result of the mechanics behind the foot and the amount of weight they are responsible for. These are the bones that the present invention focuses on fixation and stabilizing for rejuvenation, and insertion of an implant or intramedullary nail 10 through them as an embodiment of the invention. If either of the two bones are stable enough to support a locking screw, the nail is designed to have holes for that purpose, a first fastener hole 16 for the navicular bone 2 and a second fastener hole 17 for the medial cuneiform 3. These two fastener holes transverse the axial central axis (central elongated body) 13 of the nail. Finally, the first metatarsal 7 is the bone that makes up the big toe in the human foot, where the distal end 12 of the intramedullary nail 10 is attached by way of at least one fastener (or locking screw, with three depicted in FIGS. 1, 20, 19, and 18).

FIG. 2 is a side view of a left human foot, depicting the bones therein and an implant or intramedullary nail 10 running through the mid-foot region. Again, the implant or intramedullary nail 10 runs through the medullary canal of first metatarsal 7, medial cuneiform 3, navicular 2, and talus bone 1. This figure shows the phalanges bones (8 & 9) which are joined to the first metatarsal 7, at which the joint must be dislocated downward (as will be discussed below) prior to insertion of the intramedullary nail 10. Again, the nail's proximate end 11 is inserted up into the talus bone 1 far enough so that at least one proximal fastener holes (14 & 15 depicted) are within the bone.

The nail 10, being one embodiment of the present invention, must be sized (length and diameter) so that it extends far enough into the talus bone 1 to clear at least one fastener hole, and include fastener holes for the proper attachment of fasteners (locking screws) in the remaining bones, at least one fastener hole (with three depicted in the FIGS. 20, 19, & 18) for attaching and locking the nail to the first metatarsal 7, and optionally, a first fastener hole 16 for the navicular bone 2 and a second fastener hole 17 for the medial cuneiform 3.

A second embodiment of the present invention is the method by which a device (such as an intramedullary nail as depicted in FIG. 1 & FIG. 2) may be used and inserted into and through the mid-foot region to support damaged or deteriorating bones therein. The first step would consist of the taking of x-ray pictures of the unhealthy foot to determine the extent of the injury, and the size (length and diameter) of the device or implant (herein, intramedullary nail 10, as depicted in FIG. 1 & FIG. 2) needed for insertion. Second, dislocation of the phalanges 8 which are attached to the first metatarsal must be done to expose the head of the first metatarsal. Third, an arthrotomy of the first metatarsal 7 is done. Fourth, as an optional embodiment of the present invention, a tubular chisel system may be used to remove a plug of bone and cartilage from the underlying head of the first metatarsal (which can then be re-plugged after insertion of the nail to more rapidly promote healing and not leave a gap in the head of the bone as one skilled in the art would recognize). Fifth, closed reduction is performed on the bones in the mid-foot region which may be sagging or close to collapse as a result of deterioration or fracture. Sixth, a guide-wire is inserted through the medullary canal of first metatarsal 7, medial cuneiform 3, navicular 2, all the way into the talus 1 with use of fluoroscopy to maintain correct alignment of the foot. The first guide-wire may have a ball tip on the end to make sure the flexible reamer may be easily removed if it breaks. The seventh step consists of reaming over the guide-wire with the ball tip all the way into the talus 1. The reaming is done under fluoroscopy so that the correct depth into the talus 1 may be achieved. Reaming should be done at 0.5 mm diameter larger than the nail to be inserted. The eighth step consists of placing the appropriate sized nail into a jig apparatus with outrigger, and then inserting the nail into the first metatarsal 7, by running over a smooth guide-wire. The nail is centered into the medullary canal beginning with the first metatarsal 7, and then through the medial cuneiform 3, navicular 2, and talus 1 bones respectively. Ninth, at least one fastener (or locking screw, with two depicted in FIGS. 1, 14 & 15) is placed percutaneously into the proximal fastener hole of the nail, and into the talus bone. This procedure only requires a small stab incision, that which one “skilled in the art” would appreciate. The tenth step, is an optional step of compression that may be achieved with a nail of the type having a trocar and sleeve mechanism known in the art, or the like. A further embodiment of the present invention could include a depth gauge device which may be used to determine the amount of compression achieved, that which is determined by the width of the bone. This device would eliminate the need for guessing the correct amount of compression required, since the amount of compression could then be determined to a specific length of travel of the nail back up the canal. An in-line compression sleeve may be one means used to afford compression upon the bones in the mid-foot region. After adequate compression is achieved (that which would be known by those skilled in the art), the eleventh step involves insertion of at least one fastener (or locking screw, with three depicted in FIGS. 1, 20, 19, & 18) into the distal fastener hole(s) and also into the first metatarsal. The same process of percutaneously inserting the fasteners as noted above for the proximal end can be replicated here. Fasteners may be optionally included in slots 16 for the navicular bone 2 and 17 for the medial cuneiform 3, depending upon the condition of either of these two bones. The twelfth step consists of removing the jig and replacing the plug of bone previously removed (if such step was utilized). The joint is then reduced (relocated) and the joint capsule is repaired and the sites are all sutured.

FIG. 3 is an x-ray picture taken following an experimental procedure to insert an implant into a patient's foot with two fasteners at both the proximal and distal ends. The procedure, performed in March of 2000, is being followed-up to determine the effectiveness of the newly adapted treatment. This is the only procedure to date ever performed of its kind. Such a procedure is an embodiment of the present invention.

The implant was a small intramedullary (Smith & Nephew) nail intended for insertion in a longer bone. The fasteners were locking screws inserted into the transfixation holes and also into the talus and first metatarsal bones. Such a device is an embodiment of the present invention.
